Enhancing Informed Consent for Research and Treatment

Increased scrutiny of informed consent calls for further research into decision making by patients who may be at risk for impairments. We review interventions designed to improve patient understanding of informed consent. A number of studies, within as well as outside psychiatry, have evaluated the effectiveness of specific interventions, as well as possible “predictors” of understanding of consent, such as subject characteristics, psychiatric symptoms, and cognitive impairment. Deficits in patients’ understanding of informed consent may be partially related to poorly conceived, written, or organized informed consent materials; these deficits may be remediable with educational interventions. We find that effective interventions include corrected feedback, multiple learning trials, and more organized or simplified consent forms. Educational levels of patients generally correlate with levels of understanding. Even among individuals with psychiatric illness or cognitive impairment, deficits in understanding can be remedied with certain educational interventions. A variety of interventions can enhance understanding of informed consent.

A Conceptual Model of Medical Student Well-Being: Promoting Resilience and Preventing Burnout.

ObjectiveThis article proposes and illustrates a conceptual model of medical student well-being.MethodThe authors reviewed the literature on medical student stress, coping, and well-beingand developed a model of medical student coping termed the “coping reservoir.”ResultsThe reservoir can be replenished or drained by various aspects of medical students’ experiences. The reservoir itself has an internal structure, conceptualized as consisting of the individual’s personal traits temperament and coping style. The coping reservoir metaphor is used to highlight the dynamic nature of students’ experiences, with potential outcomes including enhanced resilience and mental health versus distress and burnout.ConclusionMedical student well-being is affected by multiple stressors as well as positive aspects of medical training. Attention to individual students’ coping reservoirs can help promote well-being and minimize burnout; formal and informal offerings within medical schools can help fill the reservoir. Helping students cultivate the skills to sustain their well-being throughout their careers has important payoffs for the overall medical education enterprise, for promotion of physician resilience and personal fulfillment, and for enhancement of professionalism and patient care. This and other models of coping should be empirically validated.

Scientific and ethical issues related to deep brain stimulation for disorders of mood, behavior, and thought

CONTEXT A 2-day consensus conference was held to examine scientific and ethical issues in the application of deep brain stimulation for treating mood and behavioral disorders, such as major depression, obsessive-compulsive disorder, and Tourette syndrome. OBJECTIVES The primary objectives of the conference were to (1) establish consensus among participants about the design of future clinical trials of deep brain stimulation for disorders of mood, behavior, and thought and (2) develop standards for the protection of human subjects participating in such studies. RESULTS Conference participants identified 16 key points for guiding research in this growing field. CONCLUSIONS The adoption of the described guidelines would help to protect the safety and rights of research subjects who participate in clinical trials of deep brain stimulation for disorders of mood, behavior, and thought and have further potential to benefit other stakeholders in the research process, including clinical researchers and device manufactures. That said, the adoption of the guidelines will require broad and substantial commitment from many of these same stakeholders.

Preliminary Evidence of a Genetic Association Between Tumor Necrosis Factor Alpha and the Severity of Sleep Disturbance and Morning Fatigue

Although fatigue and sleep disturbance are prevalent symptoms in oncology patients and their family caregivers, little is known about the factors that contribute to interindividual variability in symptom severity ratings as well as in their underlying biological mechanisms. In this study, we sought to determine whether a functional genetic variation in a prominent proinflammatory cytokine, tumor necrosis factor-alpha (TNFA-308G>A [rs1800629] promoter polymorphism) was associated with overall ratings of sleep disturbance and fatigue as well as with the trajectories of these symptoms. Over 6 months, participants completed standardized measures of sleep disturbance and fatigue. Multiple linear regression was used to assess the effect of the TNFA genotype and other covariates on mean sleep disturbance and fatigue scores. Hierarchical linear modeling was used to determine the effect of TNFA genotype on the trajectories of these symptoms. Common allele homozygotes reported higher levels of sleep disturbance (p = .09) and morning fatigue (p = .02) than minor allele carriers. Multivariate analyses demonstrated that age and genotype were predictors of both mean symptom scores and the trajectories of these symptoms. Findings provide preliminary evidence of an association between a functional promoter polymorphism in the TNFA gene and the severity of sleep disturbance and morning fatigue in oncology patients and their family caregivers.

Internet interventions for improving psychological well‐being in psycho‐oncology: review and recommendations

Too few cancer patients and survivors receive evidence‐based interventions for mental health symptoms. This review examines the potential for Internet interventions to help fill treatment gaps in psychosocial oncology and presents evidence regarding the likely utility of Internet interventions for cancer patients.

Identification of distinct depressive symptom trajectories in women following surgery for breast cancer.

OBJECTIVE Depressive symptoms, common in breast cancer patients, may increase, decrease, or remain stable over the course of treatment. Most longitudinal studies have reported mean symptom scores that tend to obscure interindividual heterogeneity in the symptom experience. The identification of different trajectories of depressive symptoms may help identify patients who require an intervention. This study aimed to identify distinct subgroups of breast cancer patients with different trajectories of depressive symptoms in the first six months after surgery. METHOD Among 398 patients with breast cancer, growth mixture modeling was used to identify latent classes of patients with distinct depressive symptom profiles. These profiles were identified based on Center for Epidemiological Studies-Depression (CES-D) scale scores completed just prior to surgery, and 1, 2, 3, 4, 5, and 6 months after surgery. RESULTS Four latent classes of breast cancer patients with distinct depressive symptom trajectories were identified: Low Decelerating (38.9%), Intermediate (45.2%), Late Accelerating (11.3%), and Parabolic (4.5%) classes. Patients in the Intermediate class were younger, on average, than those in the Low Decelerating class. The Intermediate, Late Accelerating, and Parabolic classes had higher mean baseline anxiety scores compared to the Low Decelerating class. CONCLUSIONS Breast cancer patients experience different trajectories of depressive symptoms after surgery. Of note, over 60% of these women were classified into one of three distinct subgroups with clinically significant levels of depressive symptoms. Identification of phenotypic and genotypic predictors of these depressive symptom trajectories after cancer treatment warrants additional investigation.

Depression and grief reactions in hospice caregivers: from pre-death to 1 year afterwards

BACKGROUND As the US population ages, more and more individuals will find themselves facing the demanding task of caring for terminally ill family members. Yet strikingly little is known about the emotional toll such caregiving exacts from caregivers, or how the stresses and strains of caregiving affect later grief reactions. This study examines the emotional adjustment and grief intensity of bereaved caregivers from their prebereavement (caregiving) baseline through the first year after the death and compares the effects of caregiving and subsequent bereavement on spouses and adult children. METHODS Forty-eight adult children and spousal caregivers of hospice patients and 36 controls were evaluated shortly before the deaths of their loved ones and again at 2, 7, and 13 months after their deaths. All subjects were administered the Hamilton Rating Scale for Depression, Brief Symptom Inventory, and the Texas Revised Instrument of Grief. RESULTS Depression and other indices of psychological distress are highest during the caregiving period and during the first few months after the death, before decreasing over the duration of the first year. Many symptoms of grief remain prominent as long as 13 months after the death of a parent or a spouse. There were no differences in intensity of grief, depression or other indices of distress between bereaved children and bereaved spouses. CONCLUSIONS The magnitude of the stress of caregiving may be underestimated. Depression is at least as likely to emerge in the context of caregiving as it is in the postbereavement period. Therapeutic interventions may need to take into consideration the expected distress associated with caregiving and the chronicity of grief reactions. LIMITATIONS The large dropout rate, reliance on self-report ratings and demographically homogeneous sample may limit generalizability of findings.

Identification of patient subgroups and risk factors for persistent breast pain following breast cancer surgery.

UNLABELLED Study purposes were to determine the prevalence of persistent pain in the breast; characterize distinct persistent pain classes using growth mixture modeling; and evaluate for differences among these pain classes in demographic, preoperative, intraoperative, and postoperative characteristics. In addition, differences in the severity of common symptoms and quality of life outcomes measured prior to surgery, among the pain classes, were evaluated. Patients (n = 398) were recruited prior to surgery and followed for 6 months. Using growth mixture modeling, patients were classified into no (31.7%), mild (43.4%), moderate (13.3%), and severe (11.6%) pain groups based on ratings of worst breast pain. Differences in a number of demographic, preoperative, intraoperative, and postoperative characteristics differentiated among the pain classes. In addition, patients in the moderate and severe pain classes reported higher preoperative levels of depression, anxiety, and sleep disturbance than the no pain class. Findings suggest that approximately 25% of women experience significant and persistent levels of breast pain in the first 6 months following breast cancer surgery. PERSPECTIVE Persistent pain is a significant problem for 25% of women following surgery for breast cancer. Severe breast pain is associated with clinically meaningful decrements in functional status and quality of life.

Preliminary Evidence of an Association Between a Functional Interleukin-6 Polymorphism and Fatigue and Sleep Disturbance in Oncology Patients and Their Family Caregivers

CONTEXT Fatigue and sleep disturbance are common problems in oncology patients and their family caregivers (FCs). However, little is known about factors that contribute to interindividual variability in these symptoms or to their underlying biologic mechanisms. OBJECTIVES An evaluation was done on whether genetic variation in a prominent proinflammatory cytokine, interleukin-6 (IL-6 c.-6101A>T [rs4719714]), was associated with mean ratings of evening fatigue, morning fatigue, and sleep disturbance, as well as with the trajectories of these symptoms. METHODS Over six months, participants completed standardized measures of fatigue and sleep disturbance. Linear regression was used to assess the effect of the IL-6 genotype and other covariates on mean fatigue and sleep disturbance scores. Hierarchical linear modeling was used to determine the effect of the IL-6 genotype on symptom trajectories. RESULTS Common allele homozygotes reported higher levels of evening fatigue (P=0.003), morning fatigue (P=0.09), and sleep disturbance (P=0.003) than minor allele carriers. Predictors of baseline level and trajectories of evening fatigue included age, gender, and genotype (intercepts) and baseline level of evening fatigue (slope). Predictors of baseline level and trajectories of morning fatigue included age and genotype (intercept) and age and baseline level of morning fatigue (slope). Predictors of baseline level and trajectories of sleep disturbance included age and genotype (intercept) and baseline level of sleep disturbance (slope). CONCLUSIONS Findings provide preliminary evidence of a genetic association between a functional promoter polymorphism in the IL-6 gene and severity of evening fatigue, morning fatigue, and sleep disturbance in oncology patients and their FCs.
